Not that big amount of work in that part, but I want to share with you anyway
I can’t get your movie to play.
Emm, neither do I now… Something got wrong
Not sure what you used to record it but make sure you use H.264 as a codec, or, just upload it to YouTube and then embed the URL in your post

Re-recorded/encoded your original video for you @Iyaguh
Wooow, thanks a lot!
How technically did you do that? The problem was in the codec?
No worries.
Steps;
- copy URL from your post
- paste into new tab
- prompted to download
- saved file
- opened video editing software (Camtasia in my case)
- imported your video
- exported
- editted your post
- removed your uploaded video URL
- uploaded re-recorded video
Yes, the codec is the issue, your original was H.263, it would seem these are not so browser friendly now. The re-recorded version is H.264.
My suggestion regarding YouTube was intended to be a flippant one, it’s just that when you upload to there, they will re-encode/process your video and thus, going forward it won’t be a problem ever again. Potentially, my fix above, in a few years, who knows, maybe H.264 won’t be browser friendly either - but for now - nice ship! 
Thanks, Rob!
Great explanation 
No problem, happy to help 
That’s one good looking rocket!
